You're not quite understanding the interaction between JEP-95 and JEP-65.
Bytestreams (jep-65) defines a TRANSPORT mechanism, it does not (anywhere)
define the CONTENT of that stream. JEP-95 is whats used to indicate to the
recipient what the content of the stream will be, and any other associated
meta-data (for mp3, could be name of the artists, name of the radio station,
etc..). You would write a new JEP which specifies a PROFILE for the session
which defines the meta-data and allowed "stream" transports. This is what JEP-96
If you want to define GSM transfers, or MP3 streams, you would write a JEP for
those. This makes the most sense, since my client may support JEP-65, but
doesn't know what to do with specific content coming over the stream. By having
seperate "feature" elements to check for in a disco request/response, you can
see if my client even supports the CONTENT you want to send me before you
actually attempt the transfer.
Hope that helps.
